------解决方案--------------------
SQL code
 --这里修改下
set @wherestr = @wherestr+'i.AddTime between '+convert(varchar(50),@B_Date)+' and '+convert(varchar(50),@E_Date)+' and '

------解决方案--------------------
SQL code

   set @wherestr = @wherestr+'i.AddTime between '+cast(@B_Date as varchar(30))
   +' and '+cast(@E_Date as varchar(30))+' and '
set @wherestr = @wherestr+' i.status!=-1 and i.isdeleted=0'

--楼主需要注意的是要将连接的变量看看是不是类型一致的。你的日期类型不能跟字符串连接啊
